Usain Bolt dropped a starting block on his foot this week, but it’s going to take plenty more than that to worry him in the 200-meter final Saturday.

Bolt, aiming for triple gold at the World Championships, won his first round and semifinal of the 200 meters in Luzhniki Stadium on Friday. The Jamaican is a huge favorite to take his third straight world title in the 200 on Saturday (12:05 p.m. Eastern Time, NBC).

“My foot is feeling better,” Bolt told Reuters. “It was sore, but we’ve been working on it for four days.”

Bolt has been more dominant in the 200 than the 100 during his illustrious career. He hasn’t lost the event at an Olympics or worlds since taking silver behind Tyson Gay at the 2007 World Championships when he was 21 years old.

The only time a competitor at an Olympics or worlds final lost by less than three tenths of a second since came in London, where Yohan Blake won silver .12 of a second behind Bolt.

This year’s final is missing the Olympic silver medalist Blake and reigning world silver and bronze medalists Walter Dix and Christophe Lemaitre, all due to injuries. U.S. champion Tyson Gay is also absent after failing drug tests, and Justin Gatlin, the silver medalist in the 100 in Moscow, isn’t running the 200.

Bolt was given a copy of the famous lightning bolt photo from Sunday’s 100-meter final by the BBC after winning his semifinal in 20.12.

That leaves Jamaican Warren Weir, who won bronze in London, as the silver medal favorite. Weir is the third fastest man this year behind Bolt and Gay at 19.79 seconds, though he was beaten by American Curtis Mitchell in his semifinal.

“I delivered when I needed to,” Mitchell, who ran a personal best 19.97, told Johnson on Universal Sports. “Right now I’m going to build off this and hopefully carry the U.S. in the 200 meters the next six or seven years.”

Mitchell is in the medal discussion, but it could be a Jamaican sweep with Bolt, Weir and Nickel Ashmeade. Also watch South African Anaso Jobodwana, 21, who was .01 behind Bolt in their semifinal with a personal best 20.13. Brit Adam Gemili, 19, ran back-to-back personal bests in the first round and the semifinals.

If Bolt wins a medal of any color in the 200, he will pass Michael Johnson for the second most career medals by a man at the World Championships with nine. If he wins another medal in the 4×100 relay Sunday, he will match Carl Lewis for the most. If he wins gold in both events, he will also tie Lewis for the most golds won by a man with eight.

Russian Yevgenia Medvedeva broke the record for highest women’s short program score at the Grand Prix Final on Friday.

Medvedeva, who hasn’t lost in more than one year, totaled 79.21 points in Marseille, France. That beat Mao Asada‘s 78.66 from the 2014 World Championships, the previous record under a decade-old judging system.

“I knew approximately about the record,” Medvedeva said through a translator. “For me, it’s one step further.”

Medvedeva leads Canadian Kaetlyn Osmond by 3.67 points going into Saturday’s free skate. No U.S. woman qualified for the six-skater Grand Prix Final for the first time since 2008.

She already holds the free skate world record and can break Yuna Kim‘s record for total score with a solid effort Saturday in Marseille. Medvedeva said she can perform better than she did Friday, specifically with her program interpretation and spins.

“I always strive for perfection,” she said through a translator. “When you stop doing that, you will stop progress.”

The Grand Prix Final concludes with the women’s and men’s free skates and free dance Saturday (schedule here). NBCSN will air coverage Sunday from 8:30-11 p.m. ET.

Earlier Friday, Russians Yevgenia Tarasova and Vladimir Morozov held onto their short-program lead to win the pairs event by 7.14 points over China’s Yu Xiaoyu and Zhang Hao.

Canadians Meagan Duhamel and Eric Radford, the two-time world champions and pre-event favorites, struggled in the short program and free skate and lost for just the second time in the last three seasons.

In the short dance, Canadians Tessa Virtue and Scott Moir recorded the highest score of all time, an 80.50, to take a 2.53-point lead into Saturday’s free dance.

That Virtue and Moir lead is no surprise — they were the top couple in the fall Grand Prix season — but their closest challenger is a surprise.

It is not two-time world champions Gabriella Papadakis and Guillaume Cizeron of France, but instead Americans Maia and Alex Shibutani, who totaled a personal-best short dance.

Gracie Gold struggled in all four of her competitions this fall, capped by her lowest total score in four years at a Croatian event this week, putting her under scrutiny for the U.S. Championships in six weeks.

She singled three jumps and fell twice across two programs at Golden Spin in Zagreb, Croatia, on Thursday and Friday.

Gold totaled 159.02 points for sixth place, her first time below 160 points since 2012 Skate Canada in her first season as a senior skater.

Italian Carolina Kostner, the 2014 Olympic bronze medalist, won with 196.23 points in her first full competition since the 2014 World Championships.

Earlier this fall, Gold finished last of six skaters in the free skate-only Japan Open on Oct. 1, fifth at Skate America in October and eighth at Trophée de France in November.

Gold has spoken openly about trying to mentally and physically recover from last season’s world championships, where she dropped from first after the short program to finish fourth, and taking weeks off from training in the summer offseason.

Even with the rough skates, Gold still ranks fourth among U.S. women in top scores this season, behind Ashley Wagner, Mariah Bell and Mirai Nagasu.

She could struggle — to a degree — at the U.S. Championships in January and still make the three-woman world championships team. Gold has finished first or second at all four of her senior nationals appearances.
